摘要：

Different series of Pt/Al//2O//3, Ir/Al//2O//3 catalysts, of widely varying metallic dispersions, have been supported on two aluminas, one acidic and the other weakly acidic. It has been observed that various parameters (nature of the metallic phase, acidity of the support, metallic dispersion) can modify the adsorption capacity of hydrogen sulfide on the metal at high temperature (773 K). All results can be explained by taking into account that sulfur adsorption is essentially sensitive to the electronic properties of the metal.
